AceShowbiz - Bad rumors just keep coming into Lamar Odom and Sabrina Parr's relationship less than a week after they made it Instagram official. This time, it's been reported that the new couple is not really dating as they're only faking their relationship. PEOPLE first broke the story.

A source tells the publication, "They are not dating. There is nothing romantic going on with Sabrina and Lamar. It's fake." Neither the basketball player nor the personal trainer has yet to respond to the report as of now.

Lamar made his relationship with Sabrina Instagram official last week, posting on the photo-sharing site a picture of her sitting on his lap as they posed for the camera. Over the weekend, the lovebirds hit up Craig's in Hollywood for their first public outing as a couple. For their date night, Lamar opted for a navy striped shirt and black pants while his girlfriend wore a gray animal print jumpsuit.

Recently, Lamar hit back at critics who accused him of comparing Sabrina to his ex-wife Khloe Kardashian after he shared an appreciative post about the health and life coach. Admitting to feeling "a bit disappointed" because people made the wrong assumption about his post, he clarified, "This post isn't against anyone including my ex wife that I still respect deeply. I am just PRO love. Can I do that without people feeling offended? Why does that make you mad?"

He continued in his post, which featured a photo of Sabrina flaunting her figure in a white bathing suit, "Our black women have been held down for centuries ! I am now deciding to send them and my NEW WOMAN a lot of love. My post goes out to the new leading woman in my life, that I'm gonna tell everyday how beautiful she is from the inside out."
